I told Duolingo I wanted to do the 'Insane' level of Spanish per day

My vital signs are showing good numbers, says Colm O’Regan. 

My vital signs are showing good numbers. Health is at 609. I’m on a “one day streak” and I’ve “met my goals” so far. I feel good but I know in a little while the anxiety will increase. I’ll need to get back to my phone to continue or I may start getting warnings and inquiries after my health. Two hours in and I’m already hooked on Duolingo.

Duolingo is not a sporty version of the Citroen van that stores things that don’t fit in the house. It’s a language-learning app.
